We got some delivered by GD Logs from Penshaw way. 10 bags of birch, 10 bags of oak and some kindling for £125 or summat. He has birch on special at the minute for £5 a bag. You’ll need oak as well as the birch burns quick.

Never use coal. Burns nice & hot, but produces bucket fulls of tar that line your chimney. It also makes the room smell.

Best wood to burn is either birch or beech that has been seasoned for about a year. Stay well clear of dense wood like oak, it doesn't burn well. Also stay well clear of any treated wood, as this also makes a mess of your flue.

Should be able to google up wood delivery services in your area. I'm down in Norfolk & we pay £115 for 1.5 cube. The fire has to heat two large rooms, and a standard wood basket full will last about 4 hours. Using the burner to heat the two rooms, about 144 cubic metres, will get through the 1.5 cube in about 4 weeks.
